BMW X5 Electrical System Malfunction - FIXED
HTML-код
- Опубликовано: 9 фев 2025
- The electrical system malfunction warning on a 2012 BMW X5 35i E70 is caused by compromised K CAN bus and/or PT CAN bus connections, probably due to water. Water leaks are very common on the X5 E70 and even newer models and destroy trunk control modules and other electronics.
This video has important warnings about the connections and repair.
If you have water in the trunk compartment, use your shopvac to suck it out.
Thank you!!! What a stupid design. The connections weren’t even soldered. 🤦🏼This should be a recall. I haven’t been able to drive the car for 2 months. You are my hero!!!🥇
yep. glad you fixed it. Be sure to LIKE and subscribe. THAT will really help me! THANKS!!!!!
You've Definitely Hit it right on point I've had this problem on my dad's car and just now I've fixed the problem thanks to you 😊 🍻
Wow! Your video was the first one and it is exactly what is going on right now with my ‘13 x5 35i. The compartment is full of water but thankfully all the wires are e tact. But it seems per mu husband there are computer connections in this compartment that have been getting wet. This is absolutely ludicrous to put these there …
Lala, I'm having the same issue right now just after the hurricane. Hopefully I'm just as fortunate as you
Awesome job sir! Quick question. I have E70 4.4 5.0i . My idrive knob and back up camera stopped working simultaneously. What do you think might be the issue? Thx for the answer 😊
This was my problem. Thank you for this video. Car is now running but showing Engine malfunction w/ a P21A8 code. Hopefully it’s because I started the car without the lift gate control module.
Where is this module? Also does x5 tail gate open fully by itself or am I supposed to lift it manually?

Around would be a fair repair cost for a job like this?
I found mine submerged in a pool of water. Do you think this will cause a no start/crank? That’s the problem I have. I checked the front ECM and it’s dry with no signs of damage.
I'm curious. Did you ever consider drilling a hole through the metal compartment the fills up and floods the area? Asking because I'm planning on sealing the grommets, relocating the tailgate module, etc...but I'm still scared I'll miss something the the compartment will fill up again. Figured the final safety precaution is just to remove any risk of the compartment filling up. Thoughts?
tried all that...no success ....raised the module several inches and also tried putting the module in a plastic bag. the issue is some of the water wherever it is coming from wicks DOWN the wiring harness and INTO the module, The good news is that NEW modules are now available in the $50+/- range.
additionally, there are some splice connections near the bottom of that compartment. Once they start corroding, you end up with issues a new module will not solve. I do have a video out there about those wire splice issues.
@@YuDaMan I'll look for those videos. Thanks!
07’ E70 3.0si here, same problems
Thanks i had no idea what this light meant
Thank you I will start my journey and see what happens cheers
If I were a BMW or any automotive engineer, all sensitive electronic control modules and critical connectors would be located high and dry, encased in a protective housing between the headliner and roof, or mounted high on the inner body
Yeah but then bmw would have nothing to fix for you then 😂
Can you help me my tailgate is not working my latch won’t unlock it brand new and the module brand new to and the structs I don’t hear any sound when I press the button inside and outside please
make sure the tailgate and hatch are COMPLETELY closed. re-slam the lower tailgate. I had that problem early on. Not a defect.
@@YuDaMan Everything is aligned when i closes but when Open with emergency cord the button inside works and outside works closing
@@YuDaMan Do you think it’s the jbe
@@bobbypersaud no water in the trunk compartment?
@@YuDaMan no I checked very dry
I don’t find any water there in the back but my car is taking water in the passenger front and back.
What is the name of that module? I know they're model speciffic, is it the module beside the battery or the one behind the wheel well tub?
Hkl lll it’s the auto trunk module
@@Centralcoastwraps831does the trunk fully open by itself or do I need to manually lift it up?
Where's that wire?
